Capabilities and requirements definition for power electronics based technology for secure and efficient system operation and control

The proliferation of power electronics interfaced devices (PEID) in the power system and the simultaneous decreasing number of classical rotating generation pose various operational challenges for maintaining operational reliability. JWG C2/B4.38 identified these challenges, which were then clustered in three categories. As a next step, the many capabilities of state of the art PEID were described. Finally, the JWG identified which capabilities of existing PEID could be used to mitigate some of the identified operational challenges. Practical and academic examples are provided that illustrate this mitigation capability.
